On May 26th, the results of the "Shenzhen Handletter" selection for the year 2025 were officially announced. In this selection representing the highest level of intelligent manufacturing in Shenzhen, Cleer, a high-end audio brand under Shenzhen Grandsun Electronics Co., Ltd. (hereinafter referred to as "Grandsun Electronics"), stood out with its flagship product Cleer ARC 3 Sound Arc Open AI Earphones and was successfully selected for this list of carriers of urban glory. This is not only a recognition of Cleer's product innovation strength, but also a "technology token" that Shenzhen, the innovation capital, showcases to the world.

As a key urban cultural IP developed by the Shenzhen Municipal Government, the "Shenzhen Shouxin" selection is hosted by the Shenzhen Retail Business Industry Association. Under the guidance of the Shenzhen Bureau of Industry and Information Technology and the Shenzhen Bureau of Commerce, with the theme of "Creating a Better Life in Shenzhen", after strict enterprise qualification review, online popularity PK, expert evaluation, public supervision and other processes, the benchmark product that best represents Shenzhen's innovative genes is finally selected. Cleer ARC 3 Sound Arc, with its groundbreaking open acoustic technology and AI interactive innovation, has successfully made it onto the list, showcasing the hardcore strength of "Shenzhen Intelligent Manufacturing" to the world.

Crafted with technological ingenuity, creating a new benchmark for "Shenzhen Handletter"

The selection of Cleer ARC 3 is by no means accidental. As the world's first open AI earphones released by the Cleer brand in 2024, the Cleer ARC 3 Sound Arc introduces Dolby sound effects and head tracking technology for the first time in the field of open earphones, providing a 360 ° immersive auditory experience that was previously difficult to achieve due to structural limitations. This innovation brings users a more three-dimensional, realistic, and highly interactive immersive listening experience, allowing open headphones not only to "hear the world" but also to "immerse themselves in sound".

At the level of intelligent functionality, the Cleer ARC 3 is equipped with a groundbreaking high-performance AI chip that integrates AI algorithms with high-precision 6-axis sensors to create a highly intelligent interactive experience. Users do not need to frequently manually operate during use, and can complete operations such as answering calls, switching tracks, and adjusting volume through voice commands and motion sensing, perfectly adapting to the needs of sports and fitness, driving, and home work in multiple scenarios. It is worth mentioning that its AI bidirectional high-definition call function, through AI chips and call noise reduction algorithms, can not only eliminate real-time environmental noise on the user's end, but also synchronously filter environmental noise in the other party's audio track. Even in noisy places, communication remains clear and stable; The AI sound environment constant listening function can intelligently adjust the output of low-frequency, mid frequency, and high-frequency signals according to the user's environment, achieving a dynamic balanced experience of "environment changing, listening sensation unchanged".

What's even more amazing is that the representative product of "Shenzhen Hand Letter", Cleer ARC 3 Sound Arc, has overcome the problem of active noise reduction in open headphones. For the first time, active noise reduction technology has been introduced into open headphones through self-developed AI noise reduction algorithms. Compared to traditional closed headphones that rely on physical sound insulation structures to achieve noise reduction, open headphones have long been considered difficult to achieve truly effective active noise reduction due to their "non closed" structure. Cleer has achieved a milestone breakthrough in active noise reduction in the field of open earphones by deeply integrating the powerful computing power of AI chips with self-developed noise reduction algorithms, accurately capturing and reverse canceling environmental noise. Whether in noisy subways, busy airports, gyms, or street cafes, ARC 3 allows users to maintain information perception while immersing themselves in high-quality sound effects, balancing immersion, comfort, and safety.

These innovative AI features not only greatly enhance the human-machine interaction efficiency of headphones, but also significantly expand the application boundaries of open headphones in daily life, sports, office and other fields.

In addition to technological innovation, the sustainable development concept of ARC 3 Sound Arc is also worthy of praise. As the world's first open AI earphone intelligently manufactured by a zero carbon factory, ARC 3 Sound Arc strictly adheres to the low-carbon concept throughout the entire process of raw material selection, production, and transportation. The materials used in the product are all recyclable, recyclable and environmentally friendly. The entire production process uses green energy, actively responding to the global sustainable development strategy with practical actions, and has obtained zero carbon (carbon neutrality) certification from international authoritative certification agencies Sullivan and Cecil.

The market performance is impressive, and ARC 3 has become the new favorite of headphones

Since its launch, Cleer ARC 3 has continued to lead the high-end headphone market. During the "618" e-commerce shopping festival in 2024, Cleer ARC 3 sound arc, relying on innovative functions such as master level sound quality experience and AI intelligent noise reduction, quickly became a star product in the open headphone category, helping the Cleer brand win the top 1 of the industry's cumulative turnover list in the commodity list, store list and AV appliance list on the Tiktok platform. During the "Double 11" promotion period, ARC 3 Sound Arc was successfully selected into the "Double 11 Must Buy List" of Tiktok by virtue of user reputation and strong sales volume, and has repeatedly ranked first in the AV appliance list, hot sale list and buy back list. In the year-end finale of the "Double 12" shopping festival, ARC 3 Music Arc continued to lead the way and received widespread praise from technology enthusiasts and audio enthusiasts, firmly ranking first in the hot selling and repurchase lists of the Sound and Sound Feast Audiovisual Store.

This series of outstanding performances not only demonstrates Cleer's profound insight into consumer demand, but also highlights Cleer ARC 3's leading advantage and market influence as an industry benchmark product.

Persist in innovation, Cleer creates multiple global 'firsts'

Behind these impressive achievements is Cleer's unwavering pursuit of technological innovation. As one of the few audio brands in China that has built its own acoustic laboratory, Cleer has been continuously investing in technology research and development. Relying on advanced equipment and a professional acoustic team in its own laboratory, Cleer continuously improves the sound quality performance, performance stability, and user experience of its products, striving to achieve industry-leading standards in every detail.

Driven by continuous technological accumulation and innovation, Cleer has successively launched multiple world first intelligent audio products, including the "CREXING Heart Moon", "MIRAGE Mirage", and "Cleer ARC 3 Sound Arc".

In 2025, Cleer will once again release a new open AI earphone Cleer ARC 5 with a disruptive momentum, achieving comprehensive evolution on the technical accumulation of ARC 3. As the world's first open earphone that integrates the top three audio technologies of Dolby, THX, and DTS, the ARC 5 not only achieves a breakthrough in sound field spatial perception and sound quality performance, but also features a self-developed AI intelligent agent "Tingdao" for the first time, supporting multiple mainstream AI models, bringing AI simultaneous interpretation, AI voice assistant, AI voice real-time note taking and other functions, making the earphone no longer a single listening device, but a "AI productivity on the ear". This flagship new product has become another iconic achievement of Cleer's continuous deepening of the intelligent audio track and leading industry innovation.

The reason why Cleer can continue to launch innovative products that lead the trend is inseparable from its strong and profound technical support - the solid empowerment of its parent company Grandsun Electronics.
